I didn't know that Skyrim is a Generic FPS that needs a cheap gimmick to sell copies. Oh wait it's not.
The Dash avatar is perfect for that post - her expression is just right.
To the subject - first, it pleases me immensely that in spite of the obvious bias applied to the choices, "No" is still the runaway favorite. It doesn't even matter much what the subject is - any time a poster creates an obviously biased poll, I like to see the answer he favors get trounced.
Beyond that - zombies already exist in the TES universe and they have a specific place in it. Zombie-ism (I guess?) isn't transmitted by a disease. Zombies are created when necromancers reanimate corpses (or when conjurers conjure them, though those zombies, like all other conjures, aren't really real). So within the existing framework of TES, the only way the PC could become a zombie would be to be killed, then reanimated by a necromancer.
There's another type of "zombie" already in the TES universe - the draugr - and they're set to reappear in Skyrim (they were introduced in the Bloodmoon expansion to Morrowind). However, they too become "zombies" by some process other than disease - in their case, they're cannibals who were cursed by the All-Maker. So, again, it's not really something that's available to the PC.
It would certainly be possible to insert some entirely different thing into the game that resembles zombie-ism, and make it transmitted by a disease, but honestly that seems like a deliberate contrivance meant solely to satisfy the relatively small if disproportionately vocal fans of all things zombie, and I see no point at all in bogging down the game with that. It's the sort of thing best left to modders.
